In an acidic solution, the concentration of H+ is greater than the concentration of OH-. The pH will be less than 7.
In a basic solution, the concentration of OH- is greater than the concentration of H+. The pH will be greater than 7.
In a neutral solution, the concentration of H+ ions to OH-ions will be equal, and will therefore have a pH of 7. (This is due to water autoionization, which we usually ignore because it is small in other circumstances.)
The concentration of the diluted solution will be 2.44%.
<h3>Dilution problem</h3>
From the equation of dilution:
(M1)(V1) = (M2)(V2).
where M1 = concentration before dilution, M2 = concentration after dilution, V1 = volume before dilution, and V2 = volume after dilution.
In this case:
V1 = 17.06 mL
V2 = 50.00 mL
M1 = 7.16%
M2 = ?
M2 = (M1)(V1)/(V2)
= 7.16 x 17.06/50
= 2.44%
Thus, the concentration of the diluted solution is 2.44%.

The answer is B.Desertification
Fossil Fuels will not always be around. They're a nonrenewable resource. At least for the next millennia.
Just think, in about a million years, we'll be fossil fuels.
Combustion of hydrocarbons is when C and H containing compounds are burnt in O₂
the balanced chemical reaction for combustion of C₄H₁₀ (butane) is as follows;
2C₄H₁₀ + 13O₂ ---> 8CO₂ + 10H₂O
the stoichiometry of C₄H₁₀ to CO₂ is 2;4, simplified ratio is 1:2
this means that for every 1 mole of butane used up,4 moles of CO₂ are formed
molar mass of butane - (12 g/mol *4) + (1 g/mol * 10) = 58 g/mol
58 g of butane - 1 mol
Therefore 4.37 g of butane - 1/58 g/mol * 4.37g = 0.075 mol
1 mol of butane forms --> 4 mol of CO₂
Therefore 0.075 mol of butane forms = 4 x 0.075 mol = 0.3 mol of CO₂
molar mass of CO₂ = 44 g/mol
mass of CO₂ formed = 0.3 mol * 44 g/mol = 13.2 g of CO₂ is formed
